Pitchers and catchers took their physicals Wednesday. On Thursday morning, Soriano, a native of the Domincan Republic, still hadn't reported and multiple media reports cited a problem with his visa as the cause of what is expected to be a short-term delay.

Soriano signed as a free agent and is expected to be the primary closer. He served in that role for the New York Yankees last season, replacing injured ninth-inning man Mariano Rivera, and then declined a player option to remain in New York for 2013. He saved 42 games with a 2.26 ERA in 69 appearances last season.
